WIPER / WASHER: WIPER AND WASHER SYSTEM: TERMINALS OF ECU

1. CHECK DRIVER SIDE JUNCTION BLOCK ASSEMBLY AND MAIN BODY ECU (MULTIPLEX NETWORK BODY ECU)

(a) Remove the main body ECU (multiplex network body ECU) Removal.

(b) Measure the voltage and resistance according to the value(s) in the table below.

If the result is not as specified, there may be a malfunction in the wire harness.

(c) Install the main body ECU (multiplex network body ECU).

(d) Measure the voltage according to the value(s) in the table below.

If the result is not as specified, the main body ECU (multiplex network body ECU) or driver side junction block assembly may have a malfunction.

(e) Using an oscilloscope, check waveform 1.

Waveform 1 (Reference)

(f) Using an oscilloscope, check waveform 2.

Waveform 2 (Reference)

2. CHECK MULTIPLEX NETWORK DOOR ECU (BACK DOOR P/W)

(a) Disconnect the V2 multiplex network door ECU (back door P/W) connector.

(b) Measure the voltage and resistance according to the value(s) in the table below.

HINT
Measure the values on the wire harness side with the connector disconnected.

If the result is not as specified, there may be a malfunction in the wire harness.

(c) Reconnect the V2 multiplex network door ECU (back door P/W) connector.

(d) Measure the voltage according to the value(s) in the table below.

If the result is not as specified, the multiplex network door ECU (back door P/W) may have a malfunction.

(e) Using an oscilloscope, check waveform 1.
